Whiplash claim —
what you need to know.
What whiplash is, who can claim, what the compensation figures are, and — critically — the one thing that determines the value that every online calculator fails to explain.
Whiplash is the most common injury from road traffic accidents in England and Wales. Approximately 350,000 motor injury claims are made each year — the majority involving some form of soft tissue injury to the neck, back or shoulders.
Since May 2021, compensation for whiplash injuries in road traffic accident claims has been governed by a fixed government tariff. The amount is no longer decided by a judge weighing the specific circumstances of each case — it is determined by a single variable: how long the medical examiner believes the symptoms will last.
Understanding that one fact — and what it means for how claims work in practice — is the foundation for everything else on this page.
What whiplash is — and what it is not
The legal definition matters. It determines whether the fixed tariff applies to a claim or whether a different valuation framework is used.
Whiplash is a soft tissue injury caused by rapid forward and backward movement of the head and neck — typically from a rear-end collision. The sudden force strains the muscles, tendons and ligaments in the neck, back and shoulders. It does not involve fractures or damage to the spine itself.
Common symptoms include neck pain and stiffness, restricted movement, headaches, shoulder pain, pain in the upper back and arms, and occasionally nausea or dizziness. Symptoms from anxiety about driving or disrupted sleep are also recognised as associated effects of the injury.
For the purposes of the whiplash tariff, whiplash is defined in the Civil Liability Act 2018 as a soft tissue injury or a sprain, strain, tear, rupture or lesser damage of a muscle, tendon or ligament in the neck, back or shoulder, caused by or arising from a road traffic accident. This is broader than colloquial use of the term — it covers most soft tissue injuries to the upper body from an RTA, not only neck injuries.
This definition matters because the tariff applies to this specific injury type. Where injuries fall outside this definition — fractures, nerve damage, knee injuries, wrist injuries — they are not whiplash under the Act and are not valued using the tariff. They may still be claimable, but through a different valuation route.
A persistent narrative — one that appears frequently in insurer communications — suggests that low-speed collisions cannot cause valid whiplash injuries. This is not supported by the legal framework. There is no minimum speed below which a whiplash claim is automatically invalid.
Soft tissue injuries at low speeds are medically documented and legally recognised. What matters is whether an injury occurred and whether it can be supported by medical evidence — not the speed at which the vehicles were travelling. The insurer may argue that a low-speed impact was insufficient to cause injury, but this is a liability dispute, not a legal rule.
Who can make a whiplash claim
Eligibility for the OIC portal process — and what applies in situations that fall outside it.
Both drivers and passengers injured in road traffic accidents in England and Wales have the same rights to claim for whiplash injuries. The claim is made against the insurer of the at-fault driver — not against the driver personally. This applies even where the at-fault driver is a family member or friend. A claim is always against the insurance policy, not the individual.
Passengers do not need to establish who was at fault between two drivers. Where liability is disputed between drivers, a passenger's claim remains straightforward — they were not responsible for the accident.
The standard limitation period for a personal injury claim is three years from the date of the accident. For whiplash claims, this means the claim must be submitted through the OIC portal — or court proceedings issued — before the three-year deadline. The deadline applies to starting the claim, not to settling it.
Two exceptions apply. For anyone under 18 at the time of the accident, the three-year period does not begin until their 18th birthday — giving until their 21st birthday to start proceedings. Where symptoms were genuinely delayed and not apparent at the time of the accident, the three-year period runs from the date the injury became known, not the accident date.
Cyclists, motorcyclists, pedestrians and horse riders are excluded from the OIC process. For these claimants, the small claims limit remains £1,000 — meaning legal costs can be recovered from the defendant for claims above this value. The financial calculation around representation is fundamentally different, and a solicitor is generally worth considering from the outset for claims above £1,000.
Children under 18, claims involving vehicles registered outside the UK, and cases involving untraced drivers also fall outside the standard OIC process.
What a whiplash claim is worth — the tariff
Since May 2021, whiplash compensation in England and Wales has been fixed by a government tariff. The amount is determined entirely by the prognosis period — the medical examiner's assessment of how long the symptoms will last.
The compensation amount is not determined by the accident, the speed of impact, the number of vehicles involved, or anything the claimant says to the insurer. It is determined by one thing: the prognosis period recorded in the independent medical report. That report does not exist until months into the claim process.
| Up to 3 months | £275 |
| 3 – 6 months | £565 |
| 6 – 9 months | £965 |
| 9 – 12 months | £1,510 |
| 12 – 15 months | £2,335 |
| 15 – 18 months | £3,445 |
| 18 – 24 months | £4,830 |
| Up to 3 months | £240 |
| 3 – 6 months | £495 |
| 6 – 9 months | £840 |
| 9 – 12 months | £1,320 |
| 12 – 15 months | £2,040 |
| 15 – 18 months | £3,005 |
| 18 – 24 months | £4,215 |
The difference between adjacent tariff bands is substantial. Between the 6–9 month and 9–12 month bands alone, the difference is £545 under the current tariff. Between the lowest band (up to 3 months) and the highest within the portal (18–24 months), the difference is £4,555. These are not marginal amounts — they reflect the same structure of injury, assessed at different prognosis durations.
This is why the medical report review — before the draft is approved — is the most consequential single step in a whiplash claim. The prognosis period it records places the claim in a specific band. That band produces a fixed number. The insurer then makes an offer based on that number. There is no mechanism to revisit it after approval.
The tariff figure covers compensation for the injury itself — the pain, stiffness, disruption and recovery period. It does not cover the financial losses caused by the accident. Those are claimed separately as special damages and are not capped by the tariff.
Special damages include: lost earnings if the injury prevented work, travel costs to all medical appointments, prescription charges for medication related to the injury, physiotherapy or private treatment costs, and care provided by family members during recovery. Each item requires evidence — receipts, payslips, employer letters — but none of them are limited by the tariff value.
Before 31 May 2021, whiplash compensation was assessed individually — a judge or settlement negotiation would consider the specific circumstances of the injury, including its effect on the claimant's particular life and work. Awards varied considerably and were generally higher than the current tariff figures.
The Civil Liability Act 2018 replaced this with fixed amounts following lobbying by motor insurers who argued that whiplash claims were frequently exaggerated. The tariff figures are set by Parliament and reviewed periodically — the most recent review uprated all bands by approximately 15% from 31 May 2025. The next review is expected in 2027.
What every whiplash calculator gets wrong
Online compensation calculators are ubiquitous. Most of them produce numbers. Almost none of them explain why those numbers cannot be accurate.
Every whiplash compensation calculator works the same way: it asks you how long your symptoms have lasted, then applies the tariff to produce a figure. The tariff arithmetic is correct. The fundamental problem is that the prognosis period is not how long your symptoms have lasted — it is the medical examiner's assessment of how long they are expected to last in total, recorded in an independent medical report that does not exist yet.
When you use a calculator before a medical examination has taken place, you are inputting your own guess about your prognosis. The calculator is applying the tariff to that guess. The number it produces is based on your assumption, not medical evidence. The actual figure that determines your compensation is decided months later, by an independent examiner, after a formal medical appointment.
A calculator that tells you your claim is worth a specific amount before a medical report exists is not calculating anything real. It is a number designed to prompt action — often, to enter your contact details. The actual compensation value can only be known once liability is decided, a medical report is produced, and financial losses are documented.
Claimants who believe their claim is worth a specific figure before the medical examination are less likely to engage carefully with the medical report review. If the prognosis period the examiner records is shorter than the claimant expected — placing the claim in a lower tariff band — the settlement offer will be lower than the calculator suggested. Without understanding why, claimants often accept the offer rather than scrutinise whether the report accurately reflects their experience.
The calculator creates a number. The number creates an expectation. The expectation, if not examined carefully, can become the settlement figure — even when the medical report that produced it is not fully accurate.
The tariff table in section 3 shows exactly what each prognosis band is worth. The relevant question — the one that cannot be answered before the medical examination — is which band the examiner will assign. Understanding that the examination and report review are the two critical points in the process is more useful than any calculator figure.
What can be estimated before the medical report is the special damages component — financial losses with receipts and records. These are within the claimant's control to document and are not subject to medical assessment. Keeping thorough records from the moment of the accident means this component is as accurate as possible when the offer stage arrives.
Psychological injury alongside whiplash
Many people experience anxiety, sleep disruption or distress about driving after an accident. Where these symptoms are present alongside a physical whiplash injury, the tariff structure allows a higher figure — with important distinctions about what qualifies.
The whiplash tariff includes a separate, slightly higher band for claims involving whiplash with minor psychological injury. Under government guidance, a minor psychological injury in this context is one that: occurs on the same occasion as the physical injury, is secondary in significance to the physical whiplash injury, and falls short of being a diagnosed specific phobia or clinical psychological disorder.
This covers anxiety about driving, low-level distress, occasional loss of sleep and similar effects that commonly follow a road traffic accident. These do not require a separate diagnosis — they are assessed as part of the same medical report. The compensation figure is determined by the duration of the whiplash injury, even if the psychological symptoms last a different length of time.
| Prognosis period | From May 2025 | Pre-May 2025 |
|---|---|---|
| Up to 3 months | £300 | £260 |
| 3 – 6 months | £595 | £520 |
| 6 – 9 months | £1,025 | £895 |
| 9 – 12 months | £1,595 | £1,390 |
| 12 – 15 months | £2,435 | £2,125 |
| 15 – 18 months | £3,550 | £3,100 |
| 18 – 24 months | £4,975 | £4,345 |
Where psychological symptoms are more serious — a clinical diagnosis of PTSD, a specific phobia such as a driving phobia requiring formal treatment, or a diagnosable depressive or anxiety disorder — the injury moves outside the minor psychological injury category entirely. These conditions are assessed differently and are not subject to the same tariff structure.
Similarly, where psychological symptoms persist beyond 12 months without a formal clinical diagnosis, the tariff guidance beyond 12 months does not clearly apply. Claims in this territory involve more complex assessment and are situations where regulated legal advice is the appropriate route from the outset.
The one thing that determines the value
Every variable in a whiplash claim — the accident, the insurer, the solicitor, the process — feeds into a single document. That document determines the compensation figure.
The prognosis period in the medical report determines the tariff band. The tariff band produces the compensation figure. The insurer generates the offer from that figure. Everything else — the accident circumstances, how long the insurer takes, whether a solicitor is involved — affects the process but not the fundamental arithmetic. The report is the input. The tariff is the output.
An independent medical examiner is instructed through MedCo — the accredited body that oversees medical reporting for OIC claims. The examiner is not employed by the insurer and has no financial interest in the outcome of the claim. The examination typically lasts 20 to 40 minutes. It involves questions about the accident, the symptoms, how they have affected daily life and work, and a physical assessment of movement and tenderness.
The report produced from the examination is the basis for the settlement offer. The prognosis period the examiner records places the claim in a tariff band. The entire valuation flows from that single assessment.
The examination typically takes place months after the accident — sometimes 4–6 months or longer, depending on appointment availability. By this point, symptoms may have reduced significantly from their worst period. The prognosis period is an assessment of the injury's total duration, not its current state on the day of the examination.
An accurate account of how symptoms were at their worst — the early weeks after the accident — is part of a complete picture. Effects on sleep, driving confidence, physical activities, work and household tasks are all relevant. A symptom diary kept from the time of the accident provides a contemporaneous record that supports this account at the examination.
After the examination, a draft copy of the report is provided for review before it is submitted to the portal. This review window is the single most important action in the entire claim. Factual errors in the report — a symptom that was mentioned at the examination but not recorded, a prognosis period that does not reflect what was discussed — can be raised through the portal before approval.
Once the report is approved and submitted, it cannot be changed through the standard OIC process. The insurer's offer is calculated directly from whatever the report says. Taking the time needed to read it carefully — against the account of what was actually experienced and what was said at the examination — is the most effective use of that window.
When a whiplash claim may be worth more than £5,000
The OIC tariff operates within a fixed framework that suits the majority of straightforward whiplash claims. Several circumstances take a claim outside that framework — with potentially significant consequences for its value.
The whiplash tariff applies only to injuries with a prognosis period of up to 24 months. Where symptoms are expected to last longer — or where they persist beyond two years — the tariff does not apply. These claims are assessed under the pre-reform valuation framework, which uses Judicial College Guidelines rather than fixed tariff amounts. The values under this framework are typically considerably higher.
A whiplash injury with a prognosis of over 24 months also exceeds the £5,000 injury damages threshold for the OIC portal. The claim exits the portal process and is handled under different rules, where legal costs can be recovered from the defendant. For these claims, representation through a solicitor is generally financially beneficial rather than a cost.
Where the accident caused both a whiplash injury and a non-whiplash injury — a knee injury, a wrist injury, broken ribs, a head injury — the tariff applies to the whiplash element, but the non-whiplash element is assessed separately and is not capped by the tariff. The total claim may exceed the portal's thresholds even where the whiplash component alone would not.
This is the most common claim type — in the final quarter of 2024, approximately 69% of OIC claims involved mixed injuries. It is also the area where the OIC process has the most operational difficulties. Where non-whiplash injuries are significant, the total claim value, including financial losses, may approach or exceed the portal threshold. These situations benefit from early assessment of the full claim picture.
Within the OIC process, the tariff value can be increased by up to 20% where the circumstances are exceptional. This provision exists for cases where the injury has had a particularly severe impact — an injury in the highest tariff band that has profoundly affected the claimant's life and work beyond what the standard band reflects.
The threshold for exceptional circumstances is set deliberately high. It is not intended to apply broadly to all serious injuries within a band — it applies to cases where the impact is genuinely exceptional relative to others at the same prognosis level. In practice, it is applied in a minority of claims. The examiner's report and the evidence of impact on daily life are the basis for an uplift argument.
For a straightforward whiplash-only claim with a prognosis under 24 months, where liability is uncontested and financial losses are modest, the OIC process is designed to be navigable without a solicitor. ClaimTalk's guidance covers this process in detail.
For claims involving symptoms lasting over 24 months, significant non-whiplash injuries, disputed liability, a claim value that may exceed the portal threshold, or a formal psychological diagnosis — regulated legal advice from the outset is the appropriate route. These circumstances involve complexity and potential value that the standard OIC guidance does not fully cover.
